SLIDING-DOOR FASTENER.

SPECIFICATION forming part of Letters Patent Nou 705,529, dated July 22,1902. Application filed November 13, 1901. Serial No- 82,092. (Nomodel.)

To atZZ whom it may concern.-

Be it known that I, JOHN T. HICKS, a citizen of the United States ofAmerica, and a resident of the city of Boston, county of Suffolk, andState of Massachusetts,haveinvented certain new and useful Improvementsin Sliding- Door Fasteners, of which the following is a specification.

This invention relates to means for fastening or securing a slidingdoor, being principally designed to fasten sliding doors of showcases.An example of door to which it may be applied is the three-slidearrangement commonly found at the rear of a glass show-case, where thedoors slide over each other in such a manner as to permit access to anydesired point within the case.

The invention consists in certain improvements upon the sliding-doorfastener shown and described in my copending application for LettersPatent, filed February 21, 1901, Serial No. 48,239, on which I haveobtained Letters Patent No. 686,732, dated November 19, 1901, and it maybe said to comprise certain details and peculiarities in construction,combination, and arrangement, substantially as will be hereinafterdescribed and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is aperspective View of a show-case whose doors are provided with my presentnovel and useful fastener. Fig. 2 is an enlarged perspective view of theseveral parts separated from each other and shown in detail. Fig. 3 is asectional detailed plan view of the several parts arranged in operativerelation toeach other. Fig. 4 is a detailed View of the tubular bushingin the door.

Similar numerals of reference denote like parts in the difierentfigures.

In the example of sliding door illustrated and described herein, 1denotes a show-case having the rear doors 2, 3, and 4, 3 being themiddle one and being so situated with reference to the other two that alocking-bar 5 can be secured to the face thereof with its ends betweenthe vertical opposing edges of doors 2 and 4, and when so situated theparts will all be securely fastened together and the showcaseeffectually protected against any unauthorized entry which might occurin consequence of the opening of any one of the doors.

One of these doors, as 3, is provided near its bottom edge with aperforation or transverse passage, which is lined by a tubular bushing8, having therein the passage 7 and also having on the outer face of thedoor a circular flange 9, that is depressed or set into a recess in theface ofthe door, while the innerend of the bushing or sleeve 8 isinternally screwthreaded and engaged by a second smaller sleeve 10,having a circular flange 11, similar to the flange 9 and operatingagainst the inner face of the door 3. The passage 7has an offset grooveor not-ch 7, and the sleeves 8 and 10, as well as their flanges, areslotted or cut out, so as to leave the groove '7 open to permit thepassage through it of the lugs on the locking-pin.

12 denotes a locking-pin, a portion of which is round and provided witha lug 13 near the outer end of the round part and a lug 14 near theopposite end of this round part. Adjacent to the round part of the pinis a square portion 15, and at the other end of the pin is a slot 16 ofthe proper size to allow thecurved locking-shank of a padlock to passthrough it; The locking bar 5 is provided with a square passage 17 ofproper size to receive the square portion 15 of the locking-pin. Thepadlock 6 may be of any convenient and preferred design and is intendedto engage the slot 16 after all the parts have been placed in fasteningposition.

When the door is to be locked, the lockingpin will be passed through thepassage 7 ,which can easily be done because the offset groove 7 a willallow the lug 13 to slide through from one side of door 3 to the otherside, and after the pin has thus been passed through the opening 7 itcan by being slightly turned on its axis, so that the lug 13 will clearthe groove 7 be brought into a position where it cannot be withdrawnfrom the passage 7 or pushed in one direction or the other, for the lug13 will efiectually prevent it from being withdrawn in one direction,while the lug let, be ing on the outer face of the door, will/efiectually prevent the pin from being thrust into the-interior of theshow-case. After the pin has been thus placed in a non-withdrawableposition the locking-bar 5 can be connected therewith by causing theslot 17 to receive the square portion 15.

Bar 5 will now be locked between the opposing edges of the doors 2 and4. After the padlock is locked to the pin 12 by being caused to engageslot 16 the bar 5 cannot be removed from the locking-pin, and all theparts will be tightly and efiectually connected together and a firmfastener for the sliding door provided.

Obviously when the door has been unfastened all the fastener parts maybe removed and there will be no unsightly projections left on the door,as nothing will be visible thereon of the fastening device except thesleeve or bushing, and it will present no objectionable appearance andno projecting parts that might be in the way of an easy shifting of thedoor in any direction the user might please. I preferably provide thebar 15 with an eye 18 in order that after the door has been unlocked thepadlock may be caused to engage said eye,or by means of said eye thepadlock, bar 5, and pin 12 may be all fastened together until the timecomes for the door to be again locked.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a sliding-door fastener, the combination with a series of doors,of a removable fastening-pin for the middle one of the series, said pinhaving means for securing it to said door, a bar for engaging said pinand adapted to have its ends engage the opposing edges of the otherdoors, together with means for securing the bar upon the pin.

2. In a sliding-door fastener, the combination with a series of doors,the middle one of which is provided with a transverse passage, of asleeve or bushing therein, a pin adapted to be inserted into the saidpassage, said pin having means for securing it to the door, alocking-bar having a slot or opening designed to engage an angularportion of the said pin and means for fastening the pin and bartogether.

3. In a sliding-door fastener, the combination with a series of doors,the middle one of which is provided with a transverse passage, of asleeve or bushing in said passage, a pin having lugs thereon designed toengage the opposite faces of the door when the pin is in the saidpassage, said pin having also an angular portion and a slotted end, alocking-bar having an opening adapted to engage the angular portionofthe pin, and a padlock for engaging the slotted end of the pin after thebar has been located on the pin.

4. In a sliding-door fastener, the combina- Witnesses:
